The books are set off according to languages in the first
storeroom, next, they are grouped by classifying numbers.
(The classifying method adopted in the first storeroom is
specialized for small-and-middle-sized books.) Then they are
arrayed by numbers of the authors. (For books in Chinese,
numbers of the authors use the four-cornered code; for books
in Occidental languages, follow the Cutters Alphabetic-order
Table.) The classifying numbers and the numbers of the authors
combine to be the searching numbers for getting a book. A
certain searching number corresponds to a certain kind of
book(s). In the second storeroom the books are set off according
to the classifying method adopted by the Library of CAS in
which the orders of the books are represented by Arabic numerals.
The books in different languages are placed in different areas.
Then they are arrayed by numbers of the authors. (For books
in Chinese, numbers of the authors use the four-cornered code;
for books in Occidental languages, follow the Cutters Alphabetic-order
Table.) The classifying numbers and the numbers of the authors
combine to be the searching numbers for getting the books.
A certain searching number corresponds to a certain kind of
book(s).

2.Array of the Periodicals

The current periodicals are taken off and bound up after
being displayed in the reading room for one year. Then the
bound editions of the periodicals are deposited into the storerooms.
In the first storeroom they are grouped by languages, then
are arrayed according to classifying numbers of the periodicals.
(The classifying method adopted here is specialized for small-and-middle-sized
books.) Note: periodicals in Japanese are arrayed together
with those in Chinese. In the second storeroom the bound editions
of the periodicals in Chinese and those in Occidental languages
are arrayed respectively. The former part is done following
the order of Chinese words, whereas the later part, is done
alphabetically.

3. Classifying Method of Small-and-middle-sized Books

Its first class has 21 Subjects:
A Marxism and Leninism
B Philosophy
C Pandect of Social Science
D History
E Economy
F Politics and Social Living
G Law
H Military Affairs
I Culture and Education
J Language and Character
K Literature
L Art
M Religion and Atheism
N Pandect of Physical Science
P Mathematics, Physics and Chemical
Q Geology and Geography
R Bioscience
S Medicine and Hygiene
T Agro-technology
U-Y Technology
Z The Integrative Books

Following the conceptual relationship among the subjects
step by step, a more special, more idiographic items can be
reached. For example, the classifying number of the item “World
Physical Geography” is “Q951”? The way how
to get it from the top down is indicated as bellow:
Q Geology and Geography
Q9 Geography
Q95 Physical Geography
Q951 World Physical Geography

Following the Classifying Method of Small-and–middle-sized
Books, cataloguers of the library give each kind of book(s)
a certain classifying number. So, the books of the same item
are arrayed together, being convenient for users to get them
according to a certain item.
